🔍 Key Concepts

• INMARSAT ship earth station numbering formats and how their IDs usually begin • Difference between a traditional land-based TELEX number and a satellite terminal ID • Which systems (F77, Inmarsat‑C, Inmarsat‑FBB) are data-only vs. voice + data and how that relates to TELEX messaging

💭 Think About

• Look at the format of 436640927: does it look more like a fixed land telex number or a satellite terminal ID used at sea? • Which Inmarsat service is historically associated with store-and-forward text/telex-style messaging rather than primarily IP or voice? • Among the choices, which option is clearly NOT a satellite ship terminal at all?

✅ Before You Answer

• Verify which of the four options is a non-satellite, shore-based system • Check which Inmarsat service uses numeric terminal IDs that resemble TELEX numbers for ship stations • Confirm which Inmarsat services (F77, FBB) are mainly voice/IP broadband and less associated with classic telex addressing
